The TPA3125D2 evaluation module (EVM) consists of a single 10-W, class-D, stereo audio power
amplifier, complete with a small number of external components mounted on a printed-circuit board. The
EVM can be used to directly drive speakers with an external analog audio source as the input.
Figure 1
and Figure 2 display the top and bottom views of the EVM, respectively. For additional information, consult
the TPA3125D2 data sheet ( SLOS611 ).
